The nonparenchymal portion of the liver of parasitic adult lampreys (Petromyzon marinus L.) consists of endothelial, Kupffer, fibroblast-like, fat-storing, and granulated cells. The fenestrae of endothelial cells are not organized into sieve plates but are of highly variable size and distribution. The dimension of some fenestrae suggests the possible transport of substances of large molecular size. Small numbers of Kupffer cells possess many features of these cells observed in other vertebrates but they do not have worm-like bodies and endogenous peroxidase activity. They are involved in erythrophagocytosis and perhaps the ingestion of other foreign material but they do not store iron. Fat-storing and fibroblast-like cells share many morphological features and may be different expressions of the same cell type. These perisinusoidal cells are rich in organelles suggesting protein synthesis but the fibroblast-like cells lack fat droplets. A cell with a large Golgi apparatus and associated cytoplasmic granules resembles the pit cell described in the liver of a few other vertebrates. The morphology of nonparenchymal cells of the liver in parasitic adult lampreys does not reflect the absence of bile ducts in this organism.
寄生成年七鳃鳗（海七鳃鳗）肝脏的非实质部分由内皮细胞、库普弗细胞、成纤维细胞样细胞、贮脂细胞和颗粒细胞组成。内皮细胞的窗孔未形成筛板，而是大小和分布高度可变。一些窗孔的尺寸表明可能运输大分子物质。少量的库普弗细胞具有在其他脊椎动物中观察到的这些细胞的许多特征，但它们没有蠕虫样的体和内源性过氧化物酶活性。它们参与红细胞吞噬作用，可能还参与其他异物的摄取，但它们不储存铁。贮脂细胞和成纤维细胞样细胞具有许多形态学特征，可能是同一细胞类型的不同表现形式。这些窦周细胞富含细胞器，提示有蛋白质合成，但成纤维细胞样细胞缺乏脂滴。一个具有大型高尔基体和相关细胞质颗粒的细胞类似于在其他一些脊椎动物肝脏中描述的坑细胞。寄生成年七鳃鳗肝脏非实质细胞的形态并不反映该生物体中胆管的缺失。
